AUGUSTE HERBET, OF PARIS, FRANCE.

IRON BED.

SPEC2IIl-iICiA'JIIOLT forming part of Letters Patent No. 254,548, dated March 7, 1882.

Application filed March 15, 1881. (No model.) Patented in France August 16, 1 880.

To all whom it may concern:

' Be it known that I, AUGUSTE HERBET, a citizen of the Republic of France, residing in Paris, France, have invented certain Improvements in Cot-Beds, (for which 1 have obtained a French patent August 16, 1880,) of which the following is a specification.

In the accompanying drawings, Figure 1 is a sectional elevation of my invention in one of its forms. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of the same. Figs. 4 and 5 show two ways of keeping the mattress from the frame. Fig. 6 illustrates the position of thetable when raised, and Figs. 7 and 8.

show modifications.

The economical bed which constitutes the subject-matter of this invention consists of an elastic frame which is placed on two supports of any suitable shape.

In the annexed drawings thetwo trestles of an ordinary bed are shown. On these trestles A and B are placed two steel springs, (J and D, somewhat similar to coach-springs. These springs are slightly convex in the center and curved up or not at their extremities. (See Fig.

. the cross-piece E, corresponding to and entershort, a, the centers 0 being'carried at the end 'of an arm, b, fixed to the trestle; or the ends of the crossbar may be simply bent to a right angle, pierced with holes, and hung to the two centers 0. This mode of suspension permits,

as will be readily seen, the" frame to elongate freely. It also offers another advantage. In military beds, as shown in the drawings, it is desirable to remove and place. them against the wall when not in use. Nothing is easier with this system, since the whole frame turns on the axis 0. a

At the head of the bed a frame, Gr, ofordinary form, as light as possible, is bolted at H to the feet of the trestles, to which it is also fastened by the two ties I. This frame serves to retain the pillow.

To finish the bed-that is'to say, to isolate the mattress from the frame and keep the cold air from coming directly to it-various means maybe employed. The frame may be wrapped in canvas fixed to the sides, or, whatis better, turned down below and laced. (See Fig. 4.) A screen of wood may be placed over the elastic frame, or it may be furnished with bands of hoop-iron'or with a metal trellis crossed or not, as shown in Fig. 5. Lastly, both methods may be combined, the screen or trellis being wrapped with strong canvas. There is thus provided a space forming a cushion of air and preserving the heat. This elastic frame may be adapted to any iron bed-for example, the most simple ordinary bed composed of two uprights at the head and foot joined by a lower rigid frame. It is sufficient to adjust to the corners of the uprights convenient supports, upon which rest the two springs, taking care to allow the necessary play for the elastic frame to elongate. Fig.7 shows a bed thus constructed. Fig. 8 shows the same bed folded for convenience of transport.

The supports may be adapted to an elastic frame in such a manner as to constitute a mattress that may be placed on any bed. The same elastic frame can beused equally well as a hammock on board ship. In this latter case it can lie against the partition on the long side.

The addition of a chair and table is often required to military beds, which allow soldiers to work when the beds are lifted. The drawings show an arrangement of this sort. To the trestle B is nailed a small board, P, which serves as a seat. A table, T, is carried at the eud'of a rod of iron, which passes through a socket, K, of convenient length, and through an opening made in the cross-bar L, thus effectually guiding the said rod. When it is desired to use the table it is lifted to the desired height and slightly turned round, which engages a claw carried by the rod in the square part of a slot made in the socket. The tableis thus fixed by a bayonet-joint. Another mode of mounting consists of fixing the table on a rod of sheet-iron folded into a square. The vertical part of the rod is guided in two rectangular sockets, and carries a notch and projection. When the table is lifted the projection bears against the upper socket, and at this moment a detent lever actuated by a weight shoots into the notch and keeps the table at the desired height.

The mode of adjusting may evidently be va-' ried, as also the table can be placed under the same frame of the bed or at any other point. I prefer, however, to fix it to the movable trestle, as it can be carried to a convenient part of a room near a window.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A mattress or elastic frame composed of 25 spring-plates, as O D, suitably connected -together, and provided with means for suspending it to allow its expansion or contraction, substantially as described.

2. The combination, in a cot-bed, of the spring-plates O 1), connected together by end bands, F, with trestles A B, arm b, connectingarm a, and pivot 0, substantially as described.

3. The combination, in a cot-bed, of a trestle, as B, provided with a seat, P, and table T, said table being capable of vertical adjustment, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AUGUSTE HERBET.
